Aluminum iMac freeze with Bootcamp?

Has anyone experienced the freezing issue while running Boot Camp? My company is looking into buying quite a few of the new iMacs with the intention of running Windows XP with Boot Camp on them and i did not know if anyone has tried it or experienced freezing problems with it.

I don't use XP but I haven't had any system freezes running Windows Vista with Boot Camp, it's been very stable. The only freeze problem I had on the OS X side was the iTunes Store TV Shows page freeze that a number of people experienced. That problem was fixed with the 1.1 update.
As to other freeze problems that have been reported, I have not experienced any of those and suspect most of them are related to specific software. I also don't know if it's a widespread problem or just a few people posting a lot of messages about it. Things tend to get blown out of proportion here.

IMac freezes with beachball

Hi,
I sometimes have a situation where, during use of Logic, all of a sudden my iMac freezes with the famous beach ball. Only the mouse pointer still moves when moving the mouse, and the harddisk temperature monitor util still shows changing temperatures every couple of second. I have the impression that the harddisk become unaccessable; it happened twice while bouncing a song. A couple of months ago I had this lockup situation a couple of times in 2 or 3 days, and since it hasn't happened until today. Weird! The only solution is to press the power button for 5 seconds (at least, couldn't get it to life any other way).
Is this a known Logic issue???
By the way, the HD temperature is around 55 degrees Celcius. Is this normal??
Thanks, Jaap

Yep, only with Logic so far...
You might want to boot from the install DVD and run a verify check to see if there are any errors on the drive, also would be a good idea to repair permissions.
Doubtful it's the drive temperature... it could even be the program that's monitoring the temperature causing the problem. Logic punishes almost every section of a computer, memory, processor, hard drive...etc. It's best to not have anything else running in the background if possible.
How much memory do you have?
Also... if you're working with a lot of audio tracks, the system drive in not your best choice for recording.
OSX does a considerable amount of disk writes on it's own.

Does YOUR aluminum iMac work with Logic 8?

Hi, I have been facing Core Audio overloads with less than 5 tracks in Logic Pro 8 and have tried numerous suggestions. I have written ~6 songs even with the crashes and I want to something to give me a performance boost to see if Logic is worth it on an Imac or just a buggy trashpot. I recently of people with interfaces getting the same issue however.
I have a 2.4 ghz 24" aluminum imac with 4gigs RAM and am going to try adding these both: an Apogee Duet and an external dedicated FW800 drive in the next month.
For the dedicated audio FW800 drive I was considering a Lacie Quadra. Please come forward if you have an Aluminum Intel mac especially, due to all the firewire chipset discussion etc.
Can anyone who is very happy with their aluminum imac setup in Logic 8 please chime in? All responses are appreciated; So often we hear about problems on discussion boards, please share your smashing success story!
Thanks,
smooves

I have a 2.4 20" aluminum iMac running 50+ tracks (no freezing) with a few hundred plugins, with only 1 GB of RAM. I use a few external GLYPH Firewire drives. This system was actually a replacement from Apple for an iMac G5 that had the motherboard die 3 times in a 2 month time span. I'm very happy with it, its allowed me to get more work done. I don't understand why you're having so many overloads w/ only 5 tracks. I'd say up your buffer, but even for mixing I'm running at 256 on my buffer with 50 tracks or more and I'm fine. I've also never had Logic crash on me during recording or mixing. Only when using the score window. But since the update that hasn't happened.

24" Aluminum iMac Slow with Lion

I have a 24" Aluminum iMac - 2.8Ghz, 6GB RAM, 500GB HD... its a Spring 2008 iMac... SL was getting slow and we upgraded to Lion. The becahball comes on very frequently and takes anywhere from a minute to <insert time> to go away... i repair my permissions all the time, my SMART status says verified, i have used Onyx and nothng makes it better for good... once i repair permissions or us Onyx, it gets better for a little bit, but then back to what is now normal on our mac...
any ideas? any sugesstions?

My iMac is a mid-2007 20" 2.4ghz Core2Duo with 4gb of RAM. Your machine is better than mine. Lion will run very nicely on yours.
If you upgraded to Lion within the last few hours or a day or so, your Spotlight index is being rebuilt. Until it's done, everything will feel slow and even kind of... jerky because the CPU is being heavily used by that process. Let it finish.
In my case, even once that was done, for the next several days things felt slow and not very responsive. But after a few days, things went back to normal. This was not just my subjective experience - I still have Snow Leopard on another partition so it's easy for me to reboot to reset my expectations. I have a feeling that Lion does something in the background after an upgrade from Snow Leopard, building a Versions database or something, that bogs down the CPU until it's done - and it take a long time to get done. So have patience, give it at least a week.
Of course, repairing permissions, rotating your log files, and clearing your caches isn't going to hurt. But I recommend patience. Others have reported the same experience I described.

IMac freezes with every other click

I am new to the community and hope to find help for a big problem.
I run OS Yosemite 10.10.1 on my 2010 iMac 2.93 i7 (upgraded to 12GB RAM a year ago).
For the past 5 days it gives me the colorful wheel of death almost with every second click. I cannot open a program or search a site or move a file without the iMac freezing up. Just writing these two sentences, it froze twice for about 45 seconds, which is the average, but it can take up to 2 min before the Mac responds again. I have not changed anything on my iMac knowingly in the past few weeks.
I closed every program I don't need, shut down dropbox, Google Chrome, and any program I can imagine slows down processing speed. I cleaned my desktop, made sure I have 20% space on the HD. Since I am always suspicious of the Microsoft Office programs, particularly Outlook, I logged in with a different user name that does not use these programs. Nothing helps. I used Magician, Disk Utility, Activity monitor to see if anything looks odd, but all seems normal.
I am not that Mac literate, so I just discovered the Console that seems to log error events. This is what the last 5 min look like; it tells me I had 4000 events logged yesterday. Is this normal?
Please if anyone can advise what to check, change or do to stop this nuisance that would be awesome.
Thank You!

Basic guess:
Under utilities you have to run the disk doctor to see what is wrong with either your hard drive or backup drive - stop time machine first & check the backup drive first as that is the one that may be damaged.
Hopefully someone is online now who can post the details -
Another option is to take it in for repair to apple store or authorized apple dealer (if on warrantee of any kind)

IMac freezes with Halo UB game - after graphics firmware update

Hi
The graphics firmware update works good - the couple of things I found to freeze it work fine now.
But I have found one way to get the freeze and black screen plus the ASIC error in the system.log.
Open Halo UB 2.0.2 and set the video options to use 1920x1200. When I have it at 1344x840 or whatever, the game is fine.
But when I try to set Halo UB to 1920x1200, I get the freeze thing. Halo says it has to test the new video settings and says to hit escape if no dialog appears. Once I accept that, then the screen goes black and the freeze hits.
So I'm happy that everything's working good for all the other normal causes of the freeze. Hopefully Apple can now track down this issue.
Anyone else out there have Halo UB to try this out?
Maybe it's my Halo UB install. Mine was a fresh install this morning though.
good luck!
let me know...
thanks!

Freezes with Jedi Academy as well, freezes after iMac update, 10.5.1 install, Firmware Update (which i had to do with Pacifist)...
just Freezes and everything needs to be restarted, haven't tried the HALO thing yet, not sure if i want to push my luck...

Bootcamp Info.plist modifications do not work on iMacs with built-in Optical drives. What is year/model of your iMac?

My Early 2008 iMac freeze with no apparent reason

I have an Early 2008 iMac (2.66GHz Core 2 Duo with 4GB RAM).
Since installing Lion, sometimes the computer freezes without apparent reason.
The only thing I'm sure is that this is NOT the same as the Quicktime video problem – I wasn't watching a Quicktime video, nor a Flash website when it froze. Actually, today happened while I wasnt' doing anything: the computer was on, but I was at launch.
Anyway, what happens is really strange: the screen freeze, I can't do things like change volume, but the mouse still works – albeit without producing results on screen such as dock magnification etc. Also, while the computer was frozen a Time Machine backup occured as scheduled, and I was able to stream my computer's music to my iPhone using the Home Sharing feature.
The clock also remain frozen (at 12:51), so I looked at the logs and this is what I found:

At this point I restarted the computer using the power button.
For the record, a few months ago I replaced the hard drive thinking it could be the problem – good thing I needed more space anyway because it happened twice AFTER I replaced it.
Any help?

Welcome to Lion, I have 10.7.4 and this has been a problem every two weeks or so since 10.7.1. Fun.

IMac Freezes with opening of Mail

My iMac has been working great for the past four years, but recently it has been freezing up a lot. The internet won't work, most notably Safari, but the other application, such as word, freeze as well. There are two emails in my mail account that will not delete and instead turn grey in the inbox. When I click to open the emails they show no message but just a sender address. One is from Macy's and one is from Finish Line. Do you think these could have anything to do with my iMac issues or is it something else?

Try repairing your hard drive with disk utility, also repair your permissions. If you are still have problem you need to check your CPU and your RAM usage in activity monitor. Also check your remaining hard drive space you should have at a minimum 10% or more.

2008 iMac freezes with black and white patterns

Hi,
I'm surfing the web for a hint up and down the last 2 days w/o success.
The day before my iMac from March 2008 suddenly freezed and showed black and white pattern. A reboot doesn't help, the wheel moves for a while and then freezes. Boot into save mode doesn't work it looks like it loads but then again freezes.
Screenshot : http://img714.imageshack.us/img714/1751/1319334548189.jpg
I fear it's the gpu, is this replaceable ? I read a lot yes but seems to depend on the production year.
If iMac is not useable is it useable as an monitor only ?
If it's display is it replaceable ?
Also can someone share how much I can expect for gpu or display repair ?
Thanks for any hints.

I brought the iMac today to a service center. 1 hour later they already called me stating that the gpu is dead and they recommend to change for 780 SGD plus 127 SgD for diagnosis which is ard 910 USD (100 USD for diagnosis) :( .
What a pain. The gpu is 8800 GS after some reading well known for failure, I told that the guy and he said some do and it's still working for a year...well.. 900 bucks is some cash. Since I have all orig apple products, 3 iphones, 2 ipads and the iMac, first time I'm considering to do something not original....
I've told the guy that I have to sleep over it.
Anyone who was in the same or similar one way road ? Repair or go for hackintosh or give Apple another chance with a new Mac ?

IMac freezing with increasing frequency

For the last couple of months my iMac has been crashing with increasing frequency.
The crashes manifest as freezes and seem to random. Sometimes they happen when I'm doing Finder operations, sometimes in Safari, sometimes Mail, sometimes iTunes, sometimes any of a dozen other apps I run regularly. These freezes never seem to leave behind a crash report. Also, after I do a hard boot, sometimes the first one or two attempts to restart also result in a freeze during the startup sequence. Sometimes I only get to the startup gear, sometimes I get to the blue-screen right before the login, sometimes I get as far as half of my stickies popping up and then I freeze again. I've tried Disk Utility -> Repair Disk many, many times (normal SOP for me following a hard boot) and there are never any errors reported. Disk Permissions will occasionally find a file or two that needs to be repaired, but that never seems to make a difference. I've also run the hardware check dozens of times; no errors. I've even fsck'ed a few times to see if that reported any problems that Disk Utility didn't - all to no avail.
I've tried killing all non-essential processes and turning off all of my Login Items, but this didn't help either.
Sometimes I'll restart and everything will be just fine for days, maybe even a week or two, then all of a sudden, freeze after freeze after freeze.
Today has been particularly bad. I haven't been able to keep things going for more than about half an hour. That is, until I restarted in safe mode. In anticipation of possibly having to take my machine into the local Genius Bar (or maybe having to try a clean install), I decided to clean up my desktop and backup a bunch of critical files, etc.. Also, I'm drafting this message in safe mode, since the last two times I tried to do it from a regular boot, Safari froze the machine.
So far, no freezes in safe mode. However, no sound and other restrictions, so this is obviously not a particularly useful mode to operate in...
Before I go any further I should mention that there is another symptom that may or may not be related, but I suspect that it is. Sometimes windows get blocky noise in them. Lots of little rectangles which seem to be copied from elsewhere on the screen. If I force the window to refresh, everything will look OK again, but it might happen again immediately or it might take a while to happen again.
My initial gut reaction was that there was a memory problem in the display RAM, but as I said, the hardware check has not found anything and I tried it again, and again.
So far I have not associated these blocky windows directly with a freeze. In other words, the two events seem to be independent, though they could very well have the same root cause.
Well, that's all I can remember off the top of my head.
Frankly, I getting to be pretty sure that the problem was with the hardware until I booted in safe mode and am not seeing the problem.
I would appreciate any diagnostic advice that anyone would care to offer.

Unfortunately I have had this very experience with freezing/crashing iMacs at TWO different jobs and TWO different computers. In each case the Macs where brand new, out of the box. The first time in 2006, I had started a new job and convinced my boss (a die hard PC fan) that macs where the way to go in the art department. Reluctantly he plunked down for a 24" iMac. Within a couple of days, the crashing and freezing started, randomly at first. Then every few hours-regardless of the application load. Finally, it would run for three or four minutes, than Kaput. Applecare sent a tech who said it was a processor problem. With the processors swapped, the freezing stopped for a few days, then returned with a vengeance. Not only was it a nightmare- seeing as I had sworn up and down to the Admins that Macs where great, but our workflow in the department virtually stopped at this point. Within a week they had me back on a wonky PC. Suffice it to say, my tenure at that company was a short one. The next time about a year later was at a print shop. We had migrated our software and files from our Macbook Pro, Mac mini and g5 (which strangely enough was really slow) to a brand new 24" iMac and within three days, the whole gamut of crashing to complete freeze. It cost the company roughly
$50 000 in lost file processing that week. In both cases we had tried everything from moving the computers to a cooler room, fresh install (Tiger in the first case, Leopard in the second), you name it.
At this point I decided that I should find some work in Graphic Design that just doesn't depend on Macs. I also know a slew of people (industry & personal) with a frightening number of horror stories about their iMacs. All with the same symptoms. This has REALLY shaken my faith in Apple. And even tho I'm a fan and love the OS, I honestly don't think I'd invest in one without a serious overhaul of the line.

New 20" aluminum imac freezing.

After a few seconds, I heard the bip, bip, bip again and again. I try to type any keys on the keyboards, but nothing is happenning. the imac is freeze. They only way to stop the bip, bip, bip is to press the power button at the back of the screen.
Mac Os is up to date.
Each time, I run repair disk permission after I restart the iMac.
Can you please explaine what is going on?
Thank you,
Jean

Try the repair method from this Apple Doc: FSCK - File System Check
To start up in single-user mode
1. Restart the computer.
2. Immediately after the startup sound, press and hold both the Command (⌘) and "s" keys on your keyboard. The computer will display a series of text messages, at which time you may release these keys.   When the computer has started up, it will display a command line prompt (#). The computer is now in single-user mode.
How to Run the File System Check from the Command Line Once you have reached a command line, follow these steps to use fsck:
1. At the prompt, type: fsck -fy (NOTE: there is a space between the k and the “-”) The fsck utility will go through five "phases" and then return information about the disk's utilization and fragmentation. Once the check is finished, if no issue is found, you should see "** The volume appears to be OK."   If fsck alters, repairs, or fixes anything, it will display the message:
****** FILE SYSTEM WAS MODIFIED *****
2 - IMPORTANT: If this message appears, repeat the "fsck -fy" command until this message no longer appears. It is not unusual for your computer to require several "passes" of fsck, because first-pass repairs may uncover additional errors. Run it until you get two consecutive times with an "OK" result.
3. When fsck reports that no problems were found, type: reboot
4. Press Return.
If you can get into Single User Mode and run the file system check it might be able to fix the damage to the system that appears to have occurred. Worth a try.

Imac freezes with horizontal green lines

My Imac crashed the other day with green lines horizontally across the screen, the mouse would react and move around, but could not open any apps. We took it to get repaired at Core Mac and he said it worked fine. We brought it home today and it crashed again. I think it may be the graphics card? Can anyone help?
Thanks
Not sure what model as I cannot check right now.

I suspect a hardware problem. I'd recommend taking it to your local Apple Store or AASP. You can try to run Apple Hardware Test though in Extended Mode.
